Title: Improvements in or relating to navigation aiding radio systems
IPC: G01S1/02
Filed: 1937-11-15
Abstract: 487,302. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Nov. 15, 1937, No. 31395. Convention date, Nov. 14, 1936. [Class 40 (v)] In order to allow a navigator to keep more closely to the centre line of the route charted out by the overlapping beams from a beacon transmitter S, R1, R2, the aeroplane is fitted with two aerials or groups of aerials, each of which gives a directional response, when used alone, but a more " broadcast " response when used in combination. The aerials are mounted one on each side of the aeroplane, their individual polar diagrams being as indicated at e, f in Fig. 3. Once the machine F, Fig. 1, enters the field of the navigational beam, the two receiving aerials are switched over alternately, so that the overlapping parts, Fig. 3, provide an additional indication, which allows the pilot to fly strictly along the direct course L instead of zigzaging along the dotted-line. Specification 444,111 is referred to.

Title: Improvements in or relating to regenerative frequency dividing circuits
Inventor: CANNON JAMES ROWAN
IPC: H03B21/01
Filed: 1953-11-13
Abstract: 767,928. Frequency dividing circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Nov. 10, 1954 [Nov. 13, 1953], No. 31453/53. Class 40(6) The invention relates to regenerative modulator frequency dividers, i.e. frequency dividers in which a frequency (n + 1) f is applied via a line IL to one input of a modulator M and a beat frequency nf to the other input A1. The desired subharmonic f is selected from the modulator output by a filter F1, passing to an output line OL and also to a harmonic generator HG. The output of the harmonic generator HG contains the beat frequency nf which is selected by a filter F2 and comprises the second input to the modulator M. It is demonstrated in the Specification that it is possible for such a circuit to be self-operative when the regenerative loop is closed, irrespective of the phase-shifts round the loop, which determine the phase relationship # 0  between the input (n + 1) f and the beat nf. An expression is given for # 0  in terms of the individual phase-shifts caused by the elements in the loop. Such operation is not, however, necessarily stable, it being observed in practice that erratic fluctuations in output may occur. It is shown that the criterion determining the stability of operation is the loop modulation-depth gain/phase-shift characteristic when the beat frequency nf is replaced by a phasemodulated wave of the same carrier frequency but of variable modulation frequency an analogy being drawn with the known properties of the feedback amplifier, Fig. 2 (not shown). Thus the Nyquist diagram is applicable to the modulation, and also the gain/ frequency characteristics postulated by Bode a affording stable operation of a feedback amplifier. Specification 514,567 [Group XL] is referred to. The stability of operation of a given regenerative modulator frequency divider may be determined by breaking the loop at points A1, 2, a. wave of frequency nf being introduced at A1 and phase-modulated at varying frequency. The relative depth of modulation at A1, 2 is measured and plotted as a gain/frequency characteristic which for stability should fulfil the requirements postulated by Bode.

Title: System and apparatus for operating a submerged internal combustion engine
IPC: B60K13/00
Filed: 1945-11-22
Abstract: 602,568. Submersible engines. WILLY'SOVERLAND MOTORS, Inc. Nov. 22, 1945, No. 31483. Convention date, Jan. 4. [Class 7 (ii)] In an internal combustion engine of the kind having a conduit for conveying exhaust gases away from the engine means are provided to bias the gases from the conduit into the crankchamber of the engine so as to set up a pressure in the chamber sufficient to resist the ingress of water and thus render the engine capable of operation while immersed in water. The arrangement comprises a valve 65, Fig. 1, carried at the top of a vertical exhaust pipe 61 which is connected to an exhaust manifold 55 and, through a valve 75 and conduit 74 to a condenser 73. The condenser itself is connected to the crankchamber 16, and to a tube 82 fitted with a valve 83 leading to the intake manifold 43. The intake manifold has a flange 44 to which is fixed the lower half 45 of the housing for the carburetter 46. The vertical air intake pipe 48 is also attached to the housing. The upper part 52-of the housing has a dome 88 connected to the oil filler tube. The ignition coil and distributer are contained in a twopart housing 30, 31. The engine is normally ventilated by fresh air, the valve 75 being closed and the valves 83, 90 open. The carburetter is then supplied with air through the tube 48 and the exhaust gases pass out through the tube 61 and the valve 65. The air flows through tube 48, tube 89, oil filler tube, crank chamber, fitting 78, tube 82 and past the valve 83 into the intake manifold 43. When it is desired to run the engine under water, as in a river, valves 83 and 90 are closed and the valve 75 opened. With this arrangement a portion of the exhaust gases is byepassed through the tube 74 into the condenser 73 and thence through the tube 77 into the crank chamber. The loading of the exhaust pipe valve 65 is such that the back pressure in the exhaust system and thus the pressure of gas in the crank chamber is enough to prevent any water seeping in through faulty joints. The intake and exhaust pipes are extended to be above water even when the engine is submerged.

Abstract: 830,843. Manufacture of explosive nitric esters; preventing explosions. IMPERIAL CHEMICAL INDUSTRIES Ltd. Sept. 22. 1958 [Oct. 9, 1957], No. 31536/57. Classes 9(2) and 47 In the manufacture of explosives based on liquid explosive nitric esters in which a liquid explosive ester and water are piped separately to an emulsifier and the emulsion transported through pipes, the flow of nitric ester to the emulsifier is cut off when a hazardous change in the condition of the emulsion is indicated, and the flow of water is continued but diverted through the emulsifier and the emulsion transport pipes to a wash tank. As shown in Fig. 1 of the Provisional drawings, a supply of nitroglycerine in tank 1 is pumped by pump and metering unit 6 to an emulsifier 5 via a stop valve 8 which cuts off the flow if a fault occurs in the emulsion lines. Water from a tank 9 (which receives water from a separator 10 and/or mains) is circulated to a pump and metering unit 11 via pipes 13 and 14 to the emulsifier 5. Pipe 13 has a junction piece 15 at its head leading to a stop valve 16 and a two-way valve 17, which is normally closed so that water flows through valve 16 and line 14. A two-way valve 18 is interposed between pipe 14 and pipes 19 and 23 leading respectively to the emulsifiers and the wash tank 20. The emulsion flows from the emulsifier through pipes 21, valve 17, and pipe 22 to the separator 10 from which nitroglycerine is delivered to a mixer 7 and water to the tank 9. On the automatic closure of stop valves 8 and 16 whereby the flow of nitroglycerine to the emulsifier and of water through line 14 is stopped, water is directed from pipe 13 through 15-17 to' the pipe system 21. It thus flows counter to the normal flow of the emulsion and washes the emulsion from the system and emulsifier through valve 18 back to the wash tank 20. Specification 746,826 is referred to.

Title: Improvements in or relating to rotating or oscillating drums for drying, heating or cooling granular or powdered materials
IPC: F26B11/04
Filed: 1935-11-19
Abstract: 452,184. Drying or cooling systems. JONSSON, A. E., 49, Banergatan, Stockholm. Nov. 19, 1935, No. 32074. Convention date, Dec. 29, 1934. [Classes 29 and 34 (ii)] Rotating or oscillating drums for drying, heating or cooling granular, or powdered materials such as malt, grain, flour and the like have hollow shelf-like elements 4, 5, Figs. 1, 2, for the passage of heating or cooling media. Some of the elements 4, Fig. 2, extend longitudinally and in one or more rows concentrically with the circumference of the drum, and some 5 are arranged longitudinally and perpendicularly being directed substantially towards the centre of the drum so that all the material is stirred by the motion of the drum while a free diametrical feed channel is provided for unobstructed charging purposes. The drum 1, Figs. 1, 2, has double walled ends 2, 3. Between the ends the shelf-like elements 4, 5 extend. The heating or cooling medium is supplied by a conduit 6 leading through an attachment 7 to an extra cover plate 8 whereby the medium reaches a chamber 9 and so to the elements 4,5. It then passes-to a space 10 and jacket chamber 11 to be led off by tubes 12, 13, 31. In the attachment 7 there is a suction conduit communicating with the space 19 on one side and a suction pump 14 on the other. In the plate 8 are valves 16 covering ports 17 in such a wav bv controls 18 that the valves are opened when the material treated lies below the valves. In this way, air, carbon dioxide, and steam, may be drawn out by the suction pump. Other valves 20 are arranged round the drum maintained open by springs or other means when covered by material in the drum, but closed by controls 21 when they are above the level of the material. This air will be sucked through the material to remove carbon dioxide and steam when the drum is used for malt germinating purposes, but the admission of air is not regulated for cooling effects. The shelf-like elements 4 may be provided with transverse channels 22, Fig. 2. A feed channel 30 is provided to give unobstructed charging means. Additional partition walls 35 may be inserted in the drum at suitable distances apart. In a modification Fig. 4, the elements 4, 5 consist of tubes flattened or otherwise. The head may be slidably mounted to prevent distortion or distribution boxes flexibly connected to the tubes may be used.
